Mission Read

What this chapter is really asking from you

Cross-checked newspaper routes place three newspapers here, including the Ticket Booth Key side room, the upper broken-floor box route, and the second sewer-room box after the small ladder.

Public Secret Figurine routes agree on a figurine hidden behind the "totally normal wall" on the wooden shelves.

High-confidence schematic routes repeatedly call out the bunk-bed stop, tipped-over train, dangerous lower-water section, and vent-hidden safe.

Version Note

What this page is based on

This page was updated on April 29, 2026 using current launch-window public route material. The wording intentionally stays conservative where late-game guide detail is thinner or where stylized mission naming drifts across sources.

For patch-sensitive changes, route clarifications, or future DLC chain updates, compare this mission with the News & Patch Tracker.

FAQ

Quick answers for Cheeseball Sub

Why does Cheeseball Sub get singled out so often in route guides?

Because several collectible categories stack inside water, vent, key, and breakable-wall detours that punish autopilot.

What is the safest mindset here?

Slow down, clear branches while they are in front of you, and do not assume the sewer layout will be pleasant to backtrack mentally.

Is the figurine here well supported by current sources?

Yes. The strongest current public routes agree on the breakable-wall shelf landmark.
